The CAS Registry Mumber 6990-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,9 and 0 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 6990-78: (6*6)+(5*9)+(4*9)+(3*0)+(2*7)+(1*8)=139 139 % 10 = 9 So 6990-78-9 is a valid CAS Registry Number.
